(2) 2-axis circular interpolation drive
2-axis circular interpolation drive, and 2-axis circular interpolation drive under linear speed
constant control can be performed.
Circular interpolation is performed toward the specified coordinates from the current coordinates on
the circular curve specified by the center-point or passing-point coordinates.
Positional errors for the specified circuit curve are ± 1 LSB for center-point circular interpolation
or ± 2 LSB for passing-point interpolation.
The absolute addresses that can be specified for coordinates range from -2,147,483,647 to
+2,147,483,647 (32 bits).
The relative addresses that can be specified for coordinates range from -8,388,607 to +8,388,607
(24 bits).
As with IWDEX drive, asymmetrical acceleration/deceleration drive can be used for positioning.
